Answer:

x= -2

Step-by-step explanation:

sorry dont read this

Answer:

x= -2

Step-by-step explanation:

-2x-7=3(4x+7)

multiply numbers in parenthesis by 3

-2x-7=12x+21

move terms

-2x-12x=21+7

subtract -2x to -12x but since there negative the equation is addition. Also, add 21 to 7

-14x=28

divide both sides by -14

x= -2
